This report presents analyses of early design changes recorded on change report forms (CRFs) from the Software Cost-Reduction (SCR) project at the Naval Research Laboratory. SCR engineers are redesigning the operational flight program for the Navy's A-7E aircraft by using software engineering principles such as information hiding. The two major goals are to demonstrate the effectiveness of these techniques in developing, for example, easy to change real-time software and to provide high-quality development goals for other to follow. The first part of this report describes the SCR development goals for others to follow. The first part of this report describes the SCR development effort and examines how well it is meeting its goals. Results are presented as time-based trends and are compared to similar data reported from other projects. The second part examines the time-based ratios between SCR change data and personnel activity and the possible general use of these ratios as indicators of design progress. Two similar ratios are identified that show promise as indicators of design incompleteness.
